Please refer to FIG. 1 to FIG. 4. FIG. 1 is a diagram of an underwaterdrone 1000 according to a first embodiment of the present invention.FIG. 2 is a diagram of the underwater drone 1000 in another viewaccording to the first embodiment of the present invention. FIG. 3 is anexploded diagram of the underwater drone 1000 according to the firstembodiment of the present invention. FIG. 4 is an exploded diagram ofthe underwater drone 1000 in another view according to the firstembodiment of the present invention. As shown in FIG. 1 to FIG. 4, theunderwater drone 1000 includes a drone body 1, a horizontal propellermodule 2 and a vertical propeller module 3. The drone body 1 has alongitudinal axis X, and the drone body 1 is arranged along thelongitudinal axis X. In other words, the drone body 1 has a symmetricaxis (i.e., the longitudinal axis X), and a right-half portion of thedrone body 1 and a left-half portion of the drone body 1 are symmetricto each other relative to the longitudinal axis X.

Furthermore, the horizontal propeller module 2 is disposed on the dronebody 1 and oriented substantially parallel to the longitudinal axis X.When the underwater drone 1000 is put underwater, the horizontalpropeller module 2 is for driving the drone body 1 to move along thelongitudinal axis X. In other words, the horizontal propeller module 2is for driving the drone body 1 to move forwards (i.e., in a forwarddirection X1 along the longitudinal axis X) or backwards (i.e., in abackward direction X2 along the longitudinal axis X), and thelongitudinal axis X of the drone body 1 is analogy for a roll axis of anairplane. In addition, the drone body 1 has a drone front end 10 and adrone rear end 11, and the longitudinal axis X passes through the dronefront end 10 and the drone rear end 11.

Alternatively, the horizontal propeller module 2 is for driving torotate about a vertical axis Y perpendicular to the longitudinal axis X.In this embodiment, an amount of the horizontal propeller module 2 istwo, i.e., the horizontal propeller module 2 can include a lefthorizontal propeller module 21 and a right horizontal propeller module22, and the left horizontal propeller module 21 is identical to theright propeller module 22. In practical application, the underwaterdrone 1000 has a central processing unit (details of the centralprocessing unit is introduced later), which is coupled to the lefthorizontal propeller module 21 and the right horizontal propeller module22 of the horizontal propeller module 2. The central processing unit isable to control the left horizontal propeller module 21 to work in afirst power and control the right horizontal propeller module 22 to workin a second power different from the first power, which results inrotation of the drone body 1 about the vertical axis Y perpendicular tothe longitudinal axis X. The vertical axis Y is analogy for a yaw axisof the airplane.

In other words, the vertical propeller module 3 isdisposed closer to the drone front end 10 than the drone rear end 11.The disposal of the vertical propeller module 3 between the drone frontend 10 and the gravity center G of the underwater drone 1000 leads thedrone front end 10 to move upwardly or downwardly in advance. As aresult, setting the vertical propeller module 3 between the drone frontend 10 and the gravity center G of the underwater drone 1000 helps theunderwater drone 1000 to perform upward movement and downward movement.

Please refer to FIG. 6 and FIG. 7. FIG. 6 is a further exploded diagramof the underwater drone 1000 according to the first embodiment of thepresent invention. FIG. 7 is a further exploded diagram of theunderwater drone 1000 in another view according to the first embodimentof the present invention. As shown in FIG. 6 and FIG. 7, the drone body1 includes an upper casing assembly 7, a lower casing assembly 8 and adrone kernel 9. The lower casing assembly 8 is coupled with the uppercasing assembly 7, and an accommodating space S is formed between theupper casing assembly 7 and the lower casing assembly 8. The dronekernel 9 is installed in the accommodating space S. In this embodiment,the horizontal propeller module 2 is installed on the drone kernel 9,and the vertical propeller module 3 is installed on the drone kernel 9.

Furthermore, a side portion 71 of the upper casing assembly 7, a sideportion 81 of the lower casing assembly 8 and the horizontal propellermodule 2 cooperatively form a horizontal channel A, and the horizontalchannel A allows liquids to pass through. An upper opening 70 is formedon the upper casing assembly 7, a lower opening 80 is formed on thelower casing assembly 8, and a kernel channel 90 is formed on the dronekernel 9. The vertical propeller module 3 is installed inside the kernelchannel 90.

Furthermore, the upper casing assembly 7 includes a top housing 72 andan upper lateral housing 73. The top housing 72 has a top channelstructure 720 located in a position corresponding to the horizontalpropeller module 2, and an upper portion of the horizontal channel A issurrounded by the top channel structure 720. The upper lateral housing73 is for installing the top housing 72 with the drone kernel 9. Theupper lateral housing 73 has an upper liquid guiding portion 730, andthe upper liquid guiding portion 730 is connected to a propeller frondend 20 of the horizontal propeller module 2 and for guiding the liquidsto the upper portion of the horizontal channel A.

In summary, the underwater drone 1000 of the present invention has thehorizontal channel A and the vertical channel B. Therefore, when thedrone body 1 is driven to move along the longitudinal axis X, i.e., whenthe drone body 1 is driven to move forwards or backwards, part of theliquids passes through the horizontal channel A, which reducesresistance of liquid and facilitates movement of the underwater drone1000 along the longitudinal axis X. On the other hand, when the dronebody 1 is driven to move along the vertical axis Y, i.e., when the dronebody 1 is driven to move upwards or downwards, part of the liquidspasses through the vertical channel B, which reduces resistance ofliquid and facilitates movement of the underwater drone 1000 along thevertical axis Y. In such a manner, the underwater drone 1000 of thepresent invention enables rapidly underwater movement.

It should be noticed that the top housing 72 has a top stabilizerstructure 721 and the bottom housing 82 has a bottom stabilizerstructure 821. The top stabilizer structure 721 and the bottomstabilizer structure 821 respectively has a shape that reduces drag whenthe underwater drone 1000 moves through water, so as to stabilize thedrone body 1 of the underwater drone 1000. Furthermore, a density of theunderwater drone 1000 is designed to be substantially identical to adensity of water, which facilitates the underwater drone 1000 to diveinto the water, i.e., the downward direction along the vertical axis Y.In this embodiment, a leak hole S1 is formed on at least one of the tophousing 72 and the bottom housing 82. Furthermore, the leak hole S1 isfor discharging air inside the accommodating space S, which facilitatesto reduce buoyancy of the underwater drone 1000. In such a manner, ithelps the underwater drone 1000 to dive into the water.

In this embodiment, the upper casing assembly 7 further includes anupper filter structure 74, and the lower casing assembly 8 furtherincludes a lower filter structure 84.
